Well they've only gone and bloody cancelled it, haven't they? The one time I write something positive that the company is doing; albeit a research project and not much more than a concept, even the thought it could exist was enough to make me write in a such positive way.
Windows 7 props up the 'touch users' figures, though the vast majority of users will not have the capability of hardware to use the feature. So, with niche users such as myself and a handful spread across the market, only Windows really has the potential to compete in the touch market against the likes of iPad users.
Even then, there's no real word of dedicated Windows 7 plus touch devices to come. So even though touch is a highly useful feature to have, there isn't the technology, money or resources to maintain it outside of Windows in their books it seems.
